RETRACTED: Cell Adhesion-Dependent Control of MicroRNA Decay

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the Editor-in-Chief and Author.In this paper, we reported that the levels of specific microRNAs (miRNAs) decrease when cells are grown at low density or when cells are detached from a culture dish. Based on our results, we proposed that some miRNAs are selectively destabilized depending on the adhesion status of the cells. However, in subsequent studies, we discovered that structured miRNAs with low GC content are selectively lost during sample preparation, particularly when a small number of cells is used for RNA preparation using the standard TRIzol protocol (see the Letter to the Editor published in this issue for details). These findings provide an alternative explanation for our original data. While the original data are all reproducible, we are retracting the paper because we feel the main conclusions have been compromised. We apologize for any inconvenience this may have caused.
